There are two containers each having balls of two colours, green and red. The ratio of the green balls to the red balls in the first container is 2 : 3 and in the second container it is 2 : 1. N balls are randomly picked from the first container and transferred to the second container. The ratio of green balls to the red balls in the second container now becomes 1 : 1. However, the ratio of balls in the first container remains 2 : 3. If the number of balls in the first container is 25, then the value of N for which the final number of balls in the second container becomes 24 is

The work done by 4 men in 12 days is equal to the work done by 6 women in 10 days and is also equal to the work done by 8 children in 9 days.

Ram and Shyam normally work for 8 hours but do extra four hours on overtime. A job was done by 2 men together in 12 days in which Ram and Shyam did overtime for few days (not necessarily same number of days). It is calculated that had Ram not done her overtime, then the work would have taken 15 days to complete and corresponding value for Shyam is 20 days. How many days it would have taken for the work to complete had both men not done overtime?
